"Here are a few of the big movers, according to Milner: healthcare, which represents a fraction of a percentage point in that services component, will probably go to around 2.5 percent in the next 20 years. Transportation will go from around 5 percent to 20 percent, he said.

But with a sea change like AI, Milner — who invests in efforts to listen for intelligent life beyond earth — still tries to take the optimistic view. Instead of consuming jobs and leaving people behind, artificial intelligence will end up shifting the working population to jobs that are more suited to humans, while the things that robots do better “will go straight to them.”"
